Abstract (en)

[origin: EP0631366A2] A rear thrust bearing member (41) is disposed to be in frictional contact with an axial end face (42) of the spindle (34) supported in a cantilever fashion in the neighborhood of and on the rear side of an impeller (26). Frictional heat that is generated in this part is diffused satisfactorily with a cooling effect provided by the stirring of the impeller (26) in the pump casing and a heat diffusion effect provided by the circulating effect. Thus, the temperature rise of the frictional portions is suppressed, and adverse effects of heat on the surrounding member is prevented. <IMAGE>
